The registered nurse is discussing care of an infant diagnosed with a patent ductus arteriosus (PDA) with a nursing student. The registered nurse determines that the nursing student needs further teaching regarding a PDA when the student states that which circulatory change is a characteristic of this disorder?
This shunting allows oxygenated and unoxygenated blood to mix.
Blood is shunted to the right side of the heart.
This shunting results in increased pulmonary blood flow.
Blood is shunted to the left side of the heart.
The Correct Answer is D
A. "This shunting allows oxygenated and unoxygenated blood to mix."
Explanation: This statement is correct. In PDA, the shunting of blood between the aorta and pulmonary artery allows oxygenated and unoxygenated blood to mix, leading to decreased oxygen saturation in the systemic circulation.
B. "Blood is shunted to the right side of the heart."
Explanation: This statement is correct. In PDA, blood is shunted from the left side of the heart (aorta) to the right side of the heart (pulmonary artery).
C. "This shunting results in increased pulmonary blood flow."
Explanation: This statement is correct. PDA leads to increased pulmonary blood flow as a result of the shunting of blood from the aorta to the pulmonary artery.
D. "Blood is shunted to the left side of the heart."
Explanation:
A patent ductus arteriosus (PDA) is a congenital heart defect where the ductus arteriosus, a fetal blood vessel that normally closes shortly after birth, remains open. In PDA, blood is shunted from the aorta (left side of the heart) to the pulmonary artery (right side of the heart), resulting in increased pulmonary blood flow. Therefore, the correct statement is that "Blood is shunted to the right side of the heart."

Correct Answer is ["90"]
Explanation
The nurse should withhold the dose if the infant's apical heart rate is less than 90 beats per minute.
Digoxin is a medication that can slow the heart rate. If an infant's heart rate is already too slow, administering digoxin can increase the risk of bradycardia, a serious heart rhythm disturbance.
It's important to monitor the apical heart rate for a full minute before administering digoxin to an infant and to withhold the dose if the heart rate is below the specified threshold.
Correct Answer is ["A","C","D"]
Explanation
A.Reduce exposure to environmental organisms.
Explanation: Minimizing the child's exposure to environmental organisms helps reduce the risk of infections. This includes practices such as maintaining a clean environment and promoting good hygiene.
B. Maintain the child in a semiprivate room.
Explanation: The type of room (semiprivate or private) may not be directly related to infection control. However, maintaining a clean and controlled environment is important.
C.Use strict aseptic technique for all procedures.
Explanation: Strict aseptic technique is crucial to prevent the introduction of pathogens during procedures. This involves maintaining a sterile field and using appropriate infection control measures during medical interventions.
D.Ensure that anyone entering the child's room wears a mask.
Explanation: Wearing a mask helps prevent the spread of respiratory infections, which can be particularly risky for immunocompromised children. It is a measure to protect the child from potential airborne pathogens.
E. Apply firm pressure to a needlestick area for at least 10 minutes.
Explanation: Applying firm pressure to a needlestick area is relevant in the context of preventing bleeding or hematoma formation but is not directly related to infection control.
